Elizabethkingia meningosepticca

Bacteria, Gram-Negative


Elizabethkingia meningosepticca is a Gram-negative slightly curved rod-shaped bacterium. This organism produces large, smooth colonies on blood and chocolate agars within 24 hours. The microorganism is found worldwide in soil, river water, and reservoirs.


E.meningosepticca can cause meningitis in newborns and immune-compromised individuals. However, outbreaks are rare and usually localized to small groups. E. meningosepticca can be resistant to antimicrobial agents routinely prescribed for Gram-negative infections. However, E. meningosepticca is generally susceptible to agents that are active against Gram-positive bacteria such as rifampin and vancomycin.
